Grade Calculator

How to Use This Grade Calculator

Using this tool is pretty simple. Enter the score you got and the total possible score for each assignment or test. The calculator works out your percentage and tells you your letter grade right away.

You can add as many rows as you need — one for each quiz, homework, or exam. When you’re done, hit Calculate and you’ll see your overall grade at the bottom.

No account, no email, no waiting. It runs entirely in your browser.

Step-by-step

1. Type your score in the first box (example: 78)
2. Type the total possible points in the second box (example: 100)
3. Click Add Row if you have more than one grade to include
4. Press Calculate Grade
5. Your percentage and letter grade appear instantly

That’s it. If you made a mistake, just edit the number and the result updates automatically.

What the Results Mean

The tool shows you three things: your raw percentage, your letter grade, and a short note about where that puts you.

Here’s the standard grading scale most schools in the US use:

Percentage	Letter Grade	GPA Points
90% – 100%	A	4.0
80% – 89%	B	3.0
70% – 79%	C	2.0
60% – 69%	D	1.0
Below 60%	F	0.0

Some schools use a plus/minus system (A+, A, A−, B+, and so on). If yours does, check the FAQ section below — there’s a breakdown of those cutoffs too.

Calculating Grades by Points vs. Percentages

Both methods give you the same answer. The calculator handles either one.

By points: If you got 43 out of 50 on a quiz, enter 43 and 50. The tool divides 43 by 50 and multiplies by 100, giving you 86% — a B.

By percentage: If your teacher already gave you a percentage (say, 91%), just enter 91 in the score box and 100 as the total. You’ll get an A.

There’s no trick to it. The formula is the same one your teacher uses: (score ÷ total) × 100.

Averaging Multiple Grades Together

Say you’ve taken three tests this semester and want to know where you stand. Add each one as a separate row, and the calculator averages them out.

For example:

• Test 1: 72/100
• Test 2: 85/100
• Test 3: 90/100

That averages to 82.3% — a solid B. You’d see that result the moment you hit Calculate.

If your class uses weighted grades (where the final exam counts more than a quiz), try the Weighted Grade Calculator instead. That one lets you assign a different percentage weight to each assignment.

What Grade Do You Need to Pass?

If you’re close to the pass/fail line, it helps to know exactly what score you need on the next assignment to stay above it.

The math is straightforward. If you’re at 58% after three tests and need 60% to pass, and there’s one test left worth the same as the others, you need to score roughly 66% on that final test to clear the line.

You can test different scenarios right in the calculator — just change the numbers until the result shows the grade you’re aiming for.

Or if you already know your current grade and want to find out what you need on the final exam specifically, the Final Exam Calculator is built exactly for that.

Grading Scales Around the World

Not every country or school uses A through F. Here’s a quick reference.

United Kingdom: Universities use First Class (70%+), Upper Second / 2:1 (60–69%), Lower Second / 2:2 (50–59%), Third (40–49%), and Fail (below 40%). Use the UK Degree Grade Calculator for this.

Canada: Similar to the US but some provinces use a 9-point GPA scale or percentage only. An A is generally 80%+ rather than 90%+.

Germany: Grades run from 1 (best) to 6 (fail) — the opposite direction from the US system. A 1 or 2 is excellent; 4 is the lowest passing grade.

India: Most universities use a 10-point CGPA system or a straight percentage. 60%+ is often considered a First Class result.

This calculator uses the standard US percentage-to-letter system by default. If your school uses something different, the percentage result is still useful — just match it to your local scale.

Tips for Students Who Want to Improve Their Grade

Knowing your current grade is the first step. Here’s what actually tends to move the number.

Find out what’s weighted most. In most classes, tests and midterms count more than homework. Spending three hours on a homework assignment worth 2% matters less than spending that time studying for an exam worth 25%.

Check for missing work. A zero drags your average down faster than a bad grade. A 50% is always better than a 0%. If there are any missing assignments you can still submit, even for partial credit, do it.

Talk to your teacher early. Most teachers respect students who come in before the final week asking what they can do. Waiting until the last day rarely works out.

Use the calculator to run “what if” scenarios. Type in your current grades, then experiment with what happens if you score 80%, 85%, or 90% on upcoming work. Seeing the numbers shift in real time is weirdly motivating.
